pSivida Announces an Evaluation Agreement with Hospital for Special Surgery To Investigate Bioerodible Sustained Release Systems in Orthopedic Surgery

WATERTOWN, Mass. & NEW YORK, Aug 16, 2011 (BUSINESS WIRE) -- Drug delivery company pSivida Corp. /quotes/zigman/111048/quotes/nls/psdv PSDV +3.99% (asx:PVA) today announced it has entered into an evaluation agreement with Hospital for Special Surgery (HSS), a world leader in orthopedics, rheumatology and rehabilitation, to investigate pSivida's drug delivery technologies in orthopedics.

This agreement follows pSivida's announcement in June that it has renegotiated its collaboration agreement with Pfizer to focus solely on developing a bioerodible sustained release implant for glaucoma and ocular hypertension. (This program is already in clinical trials).

"We believe this orthopedic evaluation agreement is important for pSivida as our drug delivery technology, originally developed for ophthalmology, is being investigated in broader areas of medicine," said Dr Paul Ashton, President and CEO of pSivida. "We are excited to be working with Hospital for Special Surgery because of their long history of innovation and research in orthopaedic surgery."

About pSivida Corp.

pSivida is a world leader in the development of tiny drug delivery products that are administered by implantation, injection or insertion and provide sustained release of drugs on a controlled and level basis for months or years. The Company uses these systems to develop treatments for serious, unmet, medical needs. The Company's most advanced product candidate, ILUVIEN(R), delivers fluocinolone acetonide (FA) for the treatment of diabetic macular edema (DME). DME is a leading cause of vision loss, affecting more than a million people in the US alone, for which there is currently no FDA-approved drug therapy. ILUVIEN is licensed to Alimera Sciences, Inc., which has completed Phase III clinical trials and submitted a New Drug Application (NDA) with the Food and Drug Administration (FDA) in June 2010 based on 24-month data. In August 2010, the FDA granted Priority Review status for the NDA, and in December 2010, the FDA issued a Complete Response Letter (CRL). In February 2011, Alimera reported 36-month top-line results from the completed Phase III clinical trials and in May 2011, Alimera reported data which analyzed the subgroup of patients who had been diagnosed with DME for three or more years at entry of the study. Alimera resubmitted the NDA for ILUVIEN to the FDA on May 12, 2011 to address questions raised in the CRL and reported that data from the subgroup of patients with chronic DME was also provided together with additional information regarding controls and specifications on the manufacturing, packaging and sterlization of ILUVIEN. pSivida has two products approved by the FDA for sustained release delivery of drug to treat chronic back-of-the-eye diseases: Retisert(R) for the treatment of posterior uveitis and Vitrasert(R) for the treatment of AIDS-related cytomegalovirus (CMV) retinitis. pSivida has licensed both of these products and the technologies underlying them to Bausch & Lomb Incorporated. pSivida's intellectual property portfolio consists of over 50 patent families, more than 100 granted patents, including patents accepted for issuance, and more than 150 patent applications. pSivida conducts its operations from Boston in the United States and Malvern in the United Kingdom.
